Not every morsel of food I eat follows the primal eating plan. I don't consider it a cheat though. Cheating implies that you are being judged or graded. You aren't. The only one you have to answer to is yourself.
I follow the 80/20 principle. Basically if 80% of my food is meat, veggies, fruits, and good fats than I have room for some "fun" foods. My 20% is usually chocolate, eating out, or sugar in my coffee.
By following the 80/20 principle I keep myself sane. If I thought that I could never enjoy a glass of wine or chocolate covered strawberries again I would fall off the wagon very quickly. This way I know I can eat foods I truly enjoy as long as I use a bit of self-control.
I consider 80% to be the minimum for good health. We strive for a much higher percentage of healthy foods. We aim for about 90% by keeping our diets very clean during the week and splurging on Sunday night dinner. By planning for 90% we have a bit of wiggle room to still be above 80% if we slip up one day. After you become accustomed to this way of eating you don't want to indulge too much - you just don't feel well.
What are some of your favorite "splurge" foods?
